IV Colistin: A Rare Cause of Bartter-Like Syndrome in Adults

Abstract

Bartter syndrome is a genetic condition characterized by autosomal recessive inheritance, resulting in impaired salt reabsorption and clinical manifestations such as low/normal blood pressure and extracellular fluid volume depletion. Multiple abnormalities of the electrolytes, including decreased potassium as well as chloride levels and, in some instances, hypomagnesemia, are its defining features. Metabolic alkalosis, hypokalaemia, hypocalcemia, and hypomagnesemia, together with adequate renal function, are all components of the Bartter-like syndrome. It is associated with certain antibiotics and antineoplastic drugs. We report a case of traumatic brain injury with pneumothorax who was on treatment on colistin and presented with metabolic disturbance.
